Modernization lifecycle dates

.NET, .NET Framework, PHP, Windows Server and SQL Server support dates (end of support, mainstream, extended and Extended Security Updates), each with its primary source and the day it was checked. Each date is checked against the vendor’s own lifecycle page and cross-checked with endoflife.date.

About these dates

Each date is the vendor’s own, copied from its lifecycle page and checked on the day shown. Vendors can move dates without notice, and our copy can fall behind or contain mistakes, so confirm with the vendor before you rely on a date for a decision, contract or compliance deadline. Information only, provided as is (terms). Reuse: free to download and quote, with credit to SnowDriven and a link (terms of use).
